Options – System & Power Module DPA UPScale ST S2 Options – System & Power Module DPA UPScale ST S2 Frames Modules   Option ST40 ST60 ST80 ST120 ST200 M10 M20 System Backfeed protection • -  Power Module Battery start  - Battery charger enhancement Output short capability 3xIn Wiring Halogen free cable Mechanics Back plinth Backfeed protection (BFP) Battery Start Battery charger enhacement Output short capability 3 x In BFP in the UPS prevent the occurrence of any hazardous voltage or energy from being present on the UPS input a.c. terminals after interruption of the input a.c. power. The battery start function allows starting a UPS from the battery power in the absence of the input main supply. It means the inverter is started with energy from the battery only and the load is supplied with the battery energy via the inverter. Battery charger enhancement increases the battery charger current from 4A up to max 6A.
